g 3 Claims.

This invention relates to apparatus for the manufacture of thread or the like.

Broadly speaking, the invention is directed to apparatus comprising a trough containing liquid coagulant in which thread or the like, such, for example, as artificial silk thread or the like, is formed by a process of extrusion from a spinning nozzle; a thread-storage, thread-advancing device disposed above the trough with its receiving end generally over the trough and its discharge end extending beyond the lateral limits of said trough; and suitable takeup means; e. g., one or more thread-slaw thread-advancing devices to which the thread or the like passes from said first mentioned thread-storage,

thread-advancing device and on'which the thread or the like is subjected to processing treatment. The invention is well adapted to employment in apparatus-for the manufacture of thread or the like, such as artificial silk thread or the like, of the general type of that shown, claimed and described in prior application Serial No. 7,114, filed February 18, 1935, by Walter F. Knebusch and. Alden I-I. Burkholder.

In the drawings, forming a part hereof, Figure 1 is a sectional elevation, from line I-l of Figure 3, of a'portion of continue apparatus embodying the invention, Figure 2 is an elevation from line 2-2 of Figure 1 showing the working face of the trough, together with the apparatus associated with said trough, parts being shown as broken away. Figure 3 is an elevation from line 3-3 of Figure 1 of the. apparatus. Figure 4 is an end elevation of one form of thread-storage,

thread-advancing device which may be employed in apparatus embodying the present invention. Figure 5 is a longitudinal sectional elevation from line 5-5 of 'Figure 4 of the thread-storage, thread-advancing device of Figure 4. In the drawings,- like reference numerals refer to like parts throughout.

While the apparatus is capable of use in the manufacture of various kinds of thread or the like, as, for example, viscose, cuprammonium, nitrocellulose, or cellulose acetate artificial silk thread, it will be described hereinafter as applied to the manufacture by a continuous process of multiple filament viscose artificial silk thread.

In the apparatus illustrated, the thread I is formed by extrusion of viscose from the spinning nozzle 2 immersed in the liquid coagulating bath 3 contained in the longitudinally extending trough 4. The thread passes upward out of the bath 3 through guide 5 to the thread-storage, thread-advancing device 6 disposed above the The thread storage, thread-advancing device 6 I is preferably of a type adapted by the action of the elements thereof to-store and advance the thread axially thereof in a plurality of generally helical turns, and, as shown, may be of canti-- lever form; i. e., supported and driven from one end only, the other end being free and unobstructed. According to the present invention, the thread-storage, thread-advancing device 6 is disposed above the trough 4 with its thread-receiving end located generally over the spinning nozzle 2 and itsthread discharge end located beyond the lateral limits of the trough 4. In the embodiment shown, the thread-storage, thread-- advancing device 6 is of cantilever form and disposed with its thread-receiving end directly over the spinning nozzle and with its discharge end beyond the lateral limits of trough 4 as definedby wall 13. The thread-storage, thread-advancing device 6 is shown as mounted with its free end extending away from the working face of trough 4, defined as that face of the trough from which access may be had to the spinning nozzles, spinning pumps, etc., by an operator who, in the apparatus shown, may stand on platform I l.

The thread is withdrawn from the spinning nozzle 2 by the thread-storage, thread-advancing 6 and advanced thereby away from the working face of the trough to a point past the lateral limits of the trough, from which point it is withdrawn by a suitable device, as a succeeding thread-storage, thread-advancing device. If desired, no processing medium is applied to the thread while it is stored on the thread-storage, thread-advancing device 6 which may, under these circumstances, provide an additional period for coagulation of the thread before it is passed to a succeeding device, in addition to, performing j the functions of withdrawing the thread from the spinning nozzle in the coagulating bath and passing it to the succeeding device.

The thread-storage, thread-advancing device 6, as well as thread-storage, thread-advancing devices 8 to II of theapparatus shown may, if

desired, take the form of reels of the form illustrated in Figures 4 and 5.

This reel is of a type similar to the reel shown, described and claimed in a prior application, Serial No. 652,089 entitled Winding reel filed January 16, 1933, by' Walter F. Knebusch, to which reference may be had if desired. From Figures 4 and 5 it can be seen that each reel comprises two rigid, generally cylindrical members l5 and I6. Member 5, which may be termed the concentric member, is mounted concentrically upon and for rotation with drive shaft I1 and has its periphery comprised of a plurality of bar members l8. Member l6, which may be termed the eccentric member, is rotatably mounted with its axis slightly offset from and askew to that of concentric member l5 and has its periphery comprised of a plurality of bar members l9 equal in number 'to bar members I8 and alternately disposed therewith.

Concentric member 5 may be formed as shown, having the bar members l8 formed on the periphery of a hollow cylindrical body 2|, in which case great rigidity is imparted to the bar members I8. While member l5 may be mounted on the drive shaft H in various manners, in that shown it is held against shoulder 22 formed on drive shaft H by cap-nut 23 which is threaded on the end of reel driveshaft H. Member I5 is caused to rotate with the drive shaft H by means of a pin 24 through the shaft H, the projecting ends of which pin extend into a slot 25 formed in the hub 26 of concentric member |5. The projecting end of the drive shaft I1 and the nut 23 are thus contained within the body 2| of member l5 and therefore protected from any processing liquids which may be used.

The bar members l9 of eccentric member l6 may be provided at their outer ends with annular reinforcing rib 21, and may be supported. from a ring-like portion 28 at their inner ends. Eccentric member [6 may thus constitute an extremely rigid, generally cylindrical, cage-like member 29 mounted on a rigid annular supporting member 3|, as by bolts 32. Annular supporting member 3| is rotatably supported in offset and askew position with respect to the axis of concentric member |5 by being mounted in the desired position on frame member 33, the shaft |1 being journalled in or otherwise supported in correct relationship with frame member 33. The bushing 34 may be provided in annular supporting member 3| to act as a bearing if desired. Flexible sealing means 35 may be furnished if desired to prevent corrosion of the bearing members.

Rotation of the reel drive shaft |1 causes concentric member |5 fixed thereto to rotate, whereby contact of bar members I8 of concentric member l5 with bar members IQ of eccentric member |6 causes said eccentric member to rotate at the same angular speed. During such rotation, the offset relation with the generally cylindrical members |5 and |6 causes the thread to transfer from the bar members of one generally cylindrical member to the bar members of the other generally cylindrical member. At the same time, the askew relationship of said generally cylindrical members causes the thread to advance in a plurality of spaced, generally helical turns.

While the reels 6 may be'mounted in various ways in the desired position above the trough 4, in the arrangement shown each reel 6 is supported by a bracket 36 on which is mounted reel frame member 33. The brackets 36 are mounted on a horizontal frame member 31 which extends longitudinally above the trough 4 and is supported by vertical columns 38. Each reel 6 in the apparatus shown is rotated by a bevel gear 39 mounted on the drive shaft H of the reel, which is driven by a bevel gear 4| fixed to the short shaft 42 journalled in a bearing member 43 supported by bracket 36, to which short shaft 42 is fixed a helical gear 44 driven by a helical gear 45. The helical gears 45 for the reels 6 are adapted to be rotated by a shaft 46 extending along the frame member 31 longitudinally of the trough 4.

It has been found desirable to provide means for stopping each of the reels 6 independently of the others; therefore in the apparatus illustrated clutch means are provided to disconnect each of the reels 6 from the drive shaft 46. For this purpose, each helical gear 45 is rotatably mounted on drive shaft 46 and has mounted on it a clutch member 41 which is adapted to be engaged by a clutch member 48 slidably mounted for rotation with shaft 46. Clutch member 48 is engaged with clutch member 41 by a handle lever 49 which operates the shifter fork 5| disposed in the groove 52 of clutch member 48. It is apparent from Figures 2 and 3 that the manner shown of mounting and driving the reels 6 provides space between these reels, which is advantageous when it is desired to thread up or start the thread on the reels 6 or for other manipulation of the thread thereon.

The shaft 46 is driven by chain 53 which is driven by sprocket 54 adapted to be rotated by means of a sprocket 55 which is driven by a chain 56from a suitable source of power. The pump drive shaft 51 for the spinning pumps 58 may also be driven from sprocket 55 and chain 56. If desired suitable change speed mechanism (not shown) may be provided to adjust the speed of the pump drive shaft 51 with respect to the reels 6 and/or sprocket 55. It can be seen, in the illustrated embodiment, that the reels 6 are rotated in timed relation with the pump drive shaft 51, thus providing a constant take-up of the thread formed by extrusion of viscose through spinning nozzle 2 by the corresponding spinning pump 58, thus providing uniformity of the thread. The spinning pumps 58 may be mounted in a conventional manner on a viscose supply conduit 59 and driven from drive shaft 51 through suitablegears, each pump 58 communicating with its corresponding mass tube 6| on which is supported a spinning nozzle 2.

While the thread-storage, thread-advancing devices 8 to Il may be of any suitable form and arranged in any one of various ways, they have been shown as being of cantilever form and disposed in an arrangement similar to that described in said prior Knebusch and Burkholder application, in which they are shown as disposed in a plurality of conjugated vertical series. In each vertical series the thread-storage, threadadvancing reels are disposed in stepped arrangement with the thread receiving end of each reel adjacent the thread discharge end of the preceding reel, the open ends of the reels all facing an operator who may gain access thereto as from a ladder 63 which may be adapted for sliding movement along the face of the machine. This arrangement of the reels 8 to II provides advantages in allowing access to these reels for starting the thread thereon, inspection, repair, etc. In addition, the reels in adjacent vertical series may be disposed in corresponding positions, thus propositions in adjacent vertical series.

While more than one processing treatment may be applied to the thread on each of reels 8 to I I, inclusive, in the apparatus shown the thread is subjected to a single liquid processing treat ment on each reel. In the case of viscose thread, the thread may be desulphurized on reel 8, washed on reel 9, bleached on reel I0, washed on reel l, etc. the thread on each reel from a reagent distributor 64 positioned above the reel, said reagent distributor being supplied from a conduit 65 which may extend longitudinally of the machine and serve like reels in a horizontal series. The processing liquid may be collected in a trough 66 beneath each reel, which trough may likewise extend longitudinally of the machine and serve all corresponding reels of a horizontal series. The drain from each of the troughs 68 may communicate with a sewer in the case of liquids which it is desired to use only once, such as wash water, or with makeup and recirculating systems in the case of liquids which it is desired to re-use.

In the apparatus shown, each of the reels 8 to II, inclusive, in a single vertical series is driven from an inclined shaft 61 through

gears

68, 69. Each of the shafts 61 is mounted along the inclined/beam 10 on which are mounted the brackets H which support reels 8 to II, inclusive. Shafts 81 may be driven by a suitable driving means common to all, which means may also drive the chain 58, from which the drive shaft 46 for the reels 6 and the'pump drive shaft 5'! are driven. By such an arrangement, all of the elements of the apparatus concerned in the manui'acture and processing of thread, such as pump 68, reel 6 and reels 8 to l I, may be driven in timed relation.

It is apparent that various modifications may be made in the apparatus illustrated without in any way departing from the spirit oi the inven tion. For instance, the invention is not restricted to employment of the particular type of threadstorage, thread-advancing device illustrated, since thread-storage, thread-advancing devices of other types may be used either -for reel 6 or in place of reels 8 to II, etc. It is intended that the patent shall cover, by suitable expression in the appended claims, whatever features of patentable novelty reside in the invention. a
